Results of calculating the theoretical principles of the variational method for measuring the dielectric parameters of polar liquids: cyclopentanol and its solutions in cyclopentane have been shown in the paper. Their dielectric constant ξ' and dielectric losses ξ'' are calculated. Solutions to the equations were found and a graphical solution method and an automated method for calculating ξ' and ξ'' were developed on the basis of this method. Comparison with the results of other methods revealed that these indicators are at the same time minimal within 1.5–2.0%.

I recently published some papers (Piekara 1937 a , 1938) concerning the theory of dielectric polarization in polar liquids and their solutions in non-polar solvents. I have assumed the existence of two kinds of intermolecular coupling forces. The coupling forces of the first kind are due to the directional field produced by the surrounding molecules (ordered as in a crystal lattice) of potential energy — W 1 cos θ 1 ; θ 1 is the angular displacement of the dipole axis from the momentary axis of equilibrium, which can take all possible directions in space. This idea has been derived from R. H. Fowler (1935) and P. Debye (1935 a ), who developed with the help of this conception a theory of dielectric polarization. In order to obtain a satisfactory agreement with experiments on liquids, it proved, however, necessary to assume still a second kind of coupling forces. ‘Simultaneously it has been shown, that these latter play a more important role than the first ones. The coupling forces of the second kind are due not to aggregates of well-ordered molecules, but to the next molecule, which happens to be in the neighbourhood of the molecule just considered. As a matter of fact there are several such molecules in the vicinity, the action of which should be taken into account.
